KK2.1.5  PI gain settings Tunning Auto Level X700 Hexacopter X6

Testing my optimal settings for the Hobbyking KK2 board on my ATG X700 Hexacopter Multirotor. VERY Windy day. perfect for testing low and high motor oscillations. Using SimonK ESCs. 3S 11.1 volt 6600mAh Lipo batteries. Very smooth on windy day flying. Receiver is DEVO 10 Chanel so is Transmitter/Radio. Details below on the KK2 Board. Firmware Version: 1.6. I’ll put my PI Settings below on the comments for those who don’t want to sit through the whole video. Show some love, like and subscribe if you like it, thanks!!!

The KK2.1.5 is next big evolution of the first generation KK flight control boards. The KK2.1.5 was engineered from the ground up to bring multi-rotor flight to everyone, not just the experts. The LCD screen and built in software makes install and setup easier than ever. A host of multi-rotor craft types are pre-installed, simply select your craft type, check motor layout/propeller direction, calibrate your ESCs and radio and you’re ready to go! All of which is done with easy to follow on screen prompts!
The original KK gyro system has been updated to an incredibly sensitive 6050 MPU system making this the most stable KK board ever and allowing for the addition of an auto-level function. At the heart of the KK2.1.5 is an Atmel Mega644PA 8-bit AVR RISC-based microcontroller with 64k of memory. An additional polarity protected header has been added for voltage detection, so no need for on-board soldering. A handy piezo buzzer is also included for audio warning when activating and deactivating the board.
The KK2.1.5 added polarity protection to the voltage sense header and a fuse protected buzzer outputs, in case something is accidentally plugged in incorrectly. The voltage sense line has been updated for better accuracy. The board is clearly labeled and the voltage sense line color has been changed to red for easy identification, making installation and connections a snap.
If you’re new to multi-rotor flight or have been unsure about how to setup a KK board then the KK2.1.5 was built for you. The 6 Pin USBasp AVR programming interface ensures future software updates will be quick and easy.
